Logics for Contravariant Simulations
Abstract. Covariant-contravariant simulation and conformance simulation are two generalizations of the simple notion of simulation which aim at capturing the fact that it is not al...

A Simulation Framework for Schema-Based Query Routing in P2P-Networks
Current simulations of P2P-networks don’t take any kind of schemas into account. We present a simulation-framework and first results for query routing based on extensible schema...

Theoroidal Maps as Algebraic Simulations
Abstract. Computational systems are often represented by means of Kripke structures, and related using simulations. We propose rewriting logic as a flexible and executable framewo...

Improve Searching by Reinforcement Learning in Unstructured P2Ps
— Existing searching schemes in unstructured P2Ps can be categorized as either blind or informed. The quality of query results in blind schemes is low. Informed schemes use simpl...
